At last here are the tritium data for the two I06S cruises (1993 and 1996).
1993 Marion Dufresne Cruise Key: Samples collected, but not reported due to problem with clamps, etc. (atmospheric equilibration/contamination). Jean-Baptiste: Helium isotopes were not analysed due to clamps problems. Tritium was analysed but raw data need check before release
I would recommend both Q1 and Q2 be set to 3 in these cases. There seemed to be a large problem with the qualt1 flags on this cruise. I would replace them [flags are "9"(sample not drawn) even though values are present.] with a "3". This particular data set was reported to us well after we'd completed most of the DQE process. We used a MATLAB script to DQE the data and filtered out the CFC data flagged as "9". That means this data was not subjected to a thorough DQE process, and is therefore questionable.
Hi Mark- Sarilee and I have been working on remerging all of the CFC values in the list below. I don't think she's run into any problems, but I need to run some questions by you before I finish. I06- Has flag issues: stn 25, cst 1, btl 12 has a valid value for CFC-11 but the flags are "0" for both QUALT1 and QUALT2. This is not a valid flag value. This is also true for stn 25, cst1 btl 7 for CFC-12. Admitedly, these flags are also "0" in our online bottle file, but now would be the time to correct this. Can you advise us on what the Q2 flag should be for these values? Also in both the resubmitted CFC file and our online file, many stations exist where the flags are "9"(sample not drawn) even though values are present. Can you advise us on the Q2 flags for the updated file, so that we might correct them during the merge?
2006.11.04 DBK Rremerge of CFC's for i06sa 35MFCIVA_1 NOTES: The new CFC file sent by Mark Warner has incorrect flag values ("0") for station 25 cast 1 bottle 12 for CFC-11. station 25,cast 1,bottle 7 has incorrect flag value for CFC-12. Zero is an invalid flag value. Checked original online bottle file to find that CFC-11 had a "0" flag and CFC-12 had a "1". This station has had numerous problems with other parameters, and the entire file has had problems with parameter values, shifted columns, flags, and station truncations. Not all of which have been resolved. It appears that Sarilee did attempt to fix this particular station's problems before, however the "0" flag issue was never addressed to date. Station 25, 1, 9 had a flag of 9 for CFC both values even though valid measurements were given. As per Mark Warner, All above problem flags were changed to "3" indicating indicating a questionable measurement. Merging was completed using mrgsea with the following notes: stn, cst, btl combinations below had duplicate entries all containing -9.0 values and 9 flag: 14, 1, -9 28, 1, -9 31, 2, -9 38, 1, -9 Merged file was checked with wocecvt with no errors reported. Bottle file has been converted to .csv and netcdf with no errors.
t was decided at today's CCHDO meeting to merge or remerge CFCs for all WHP cruises in Mark Warner's CFC DQE file (Southern Ocean WHO lines). This will assure all that the CFCs for these cruises are indeed updated as intended. Danie and Sarilee will attend to this promptly. Danie will see that the sections of greatest urgency to Lynne receive top priority. The list of cruises in Mark's file was as follows: A21: EXPOCODE: 06MT11_5 A23: EXPOCODE: 74JC10_1 I06S: EXPOCODE: 35MFCIVA_1 MARGINEX: EXPOCODE: 09AR9604_1 S03_S04I: EXPOCODE: 09AR9404_1 S04A: EXPOCODE: 06AQANTIII_4 S04I: EXPOCODE: 320696_3 S04P: EXPOCODE: 90KDIOFFE6_1 SR04A_A12: EXPOCODE: 06AQANTX_4 SR04_ANTXV4: EXPOCODE: 06ANT15_4 It may be that the CFCs for the following cruises from the list above have already been updated: > sr04antxv4 > s04p > a23 > a21 But, to be certain, the CCHDO will update them as well. As far as why these cruises did not get updated with Mark's DQE'd CFCs, we have no idea. Sorry. All of the other ocean basins' CFCs were updated years ago. Jim Swift
Notes on replacing truncated I06SA CTD files. 040206/dm 1. Replaced CTD data on truncated files i06sa0006.wct, 0010, 0013.3, 0014.2, 0018, 0021, 0032, 0040, 0045, 0047, 0047.2, 0048, 0049 and 0052. using data from Sarilee Anderson's backup tape from when she did the same work in October 1998. 2. Changes regarding renaming the 1993 i06s line to i06sa to differentiate it from the 1996 i06sb line were also made. 3. New exchange file was checked with Java Ocean Atlas and new netCDF file made. NetCTF check with JOA showed missing QUALT1 word on Station 18 Cast 1 deepest level (5343db). This was not obvious on exchange file JOA check. Since P, T, S & O2 values looked good I added "2222" QUALT1 to this level. 4. Missing bottom depth on Station 42 Cast 3 required the usual work-around to convert WOCE format to Exchange format.
I found it while looking into a SUMMARY file problem. Stations 21/1 and 47/1 have WIRE OUT and MAX PRESS of 16xx while ctd data goes to over 5000db. The earliest readable SUMMARY file I found was -rwxrwx--- 1 sdiggs 60857 Feb 10 1998 i06_sum.txt There are two unreadable SUM files with the same date: -rwxrwx--- 1 sdiggs 107084 Feb 10 1998 iO6-STATION_SUM -rwxrwx--- 1 sdiggs 107084 Feb 10 1998 iO6-STATION_SUM_2 which I assume were used to make i06_sum.txt and probably have the same problem. Unless someone has a ready answer I'll leave the SUMMARY file as is and accept it as another of the many unresolved problems with the I06S data.
As noted by Bob Key and Alex Kozyr, station 25, cast 1 had the THETA and SALNTY values reversed. I corrected this and put corrected file online and made new exchange file.
Hi Steve et al., Could you please check the section I06Sa file i06sahy.txt and i06sa_hy1.csv in http://whpo.ucsd.edu/data/onetime/indian/i06/i06sa/index.htm. Something wrong with Station 25 cast 1, bottles 1-12. Seems like the data recorded in a wrong columns. Alex.
Merged the TCARBN and ALKALI for i06sa (35MFCIVA_1) retrieved from the CDIAC web site re Kozyr's e-mail. Made new exchange file. Sent notes to Jerry.
I06SA: * C14 data merged with web bottle file. * Corrections recommended by P.I. made to WOCE bottle file * Exchange file made after some suspect data removed to allow exchange file to be usable by Java Ocean Atlas. * WOCE format version will be on-line after web links modified. * Details in Notes file sent to Jerry.
Notes on I06Sa changes. July 24, 2002 D. Muus 1. SUMMARY file from web (20011024SIOWHPODMB) * Changed WOCE SECT from I06 to I06SA * No sumfile entries for Cast 2 on Stations 2, 3, 7, 9, 11, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37, 39, 41, 43, 45, 47 & 49. * Changed Cast 3 entries for above Stations to Cast 2. Sumfile entries for Cast 3 have same NO. OF BOTTLES as entries for Cast 2 in bottle file. Cast 3 entries also have "surface only" comments section. Assumed Cast 2 is rosette cast and Cast 3 is surface sample. * No sumfile entries for Stations 96-99. 2. BOTTLE file from web (no time stamp. file dated Feb 12, 1998) * Changed WHP-ID from I6 to I06SA. * Merged DELC14 abd C14ERR from: /usr/export/html-public/data/onetime/indian/i06/i06s/original/20020410_KEY_I06S_ C14/20000825.072602_KEY_I6S/20000825.072602_KEY_I6S_I6S.C14 into corrected web bottle file. * Station 12 casts 1 and 4 are missing CTD data including pressure for most entries. These casts have apparently valid water sample salinities, dissolved oxygens, CFCs, TCO2 and C14. Left data as is for WOCE format file (i06sahy.txt) but deleted casts 1 and 4 for exchange bottle file (i06sa_hy1.csv). * Station 25 cast 1 has salinity type values in the THETA column, temperature type data in the SALNTY column, one decimal place salinity type data in OXYGEN column, and other strange values in other water sample columns. Quality flags are also strange, bottle salinity flag is 6 (replicate samples) plus some 0 and 1 flags with data values. Left cast 1 in WOCE format file but deleted from exchange file. * Other quality flag problems may exist. An exhaustive check has not been done at WHPOSIO. 3. CTD * Changed WHP-ID from I06S to I06SA in all CTD headers. * Changed Cast numbers from 3 to 2 for same stations changed in sumfile. * Temperature units were "DEG C" vs ITS-68 or ITS-90; changed to "DEG_C". (Bottle file temperature labeled ITS-90.) 4. New exchange bottle and ctd files made. Stations 96-99 not in exchange files. * Sta 12, casts 1 & 4, and Sta 25 cast 1 not in bottle exchange file. 5. New files checked with Java Ocean Atlas.
I submitted a QC'ed version of the C14 from I06S_A (35MFCIVA_1), but I was not the PI (M. Arnold of CFR/CEA/CNRS was PI). The version of the data I QC'ed and submitted came from Viviane Leboucher on 2/10/99 who published these results (Leboucher, et al., 1999, Radiocarbon, 41(1), 51-73.)
Moved I6S.C14 data from /usr/export/ftp-incoming to i06/i06s/original/20020410_KEY_I06S_C14. Data is a CSV file with C14 data in it. I added the following header to the file # I06S, 316MFCIVA_1, Key
I filled out one submission form for all of the Indian Ocean C14 data then manually ftp'ed 11 cruise files to your INCOMING directory. With the exception of I6S, these should match up to the recent submission of C13 data by NOSAMS. I have QC'ed all of the C14 data and the flags are included in the files. I printed a record for every bottle from each cruise (not just those with C14), so you should get a 1 to 1 match with your files (we should be so lucky). The I6S data is from the French occupation. I think you already have this data, but I have run the file through my routine QC procedure. These data are public. I hope to get a single "Final Data Report" written very soon and will forward a pdf version.
Bottle file has been converted to exchange and put online. The following lines were removed from the bottle file for the conversion because there was no navigational information in the sumfile for them. STN 2 CAST 2 STN 3 CAST 2 STN 7 CAST 2 STN 9 CAST 2 STN 11 CAST 2 STN 15 CAST 2 STN 17 CAST 2 STN 19 CAST 2 STN 21 CAST 2 STN 23 CAST 2 STN 25 CAST 2 STN 27 CAST 2 STN 29 CAST 2 STN 31 CAST 2 STN 33 CAST 2 STN 35 CAST 2 STN 37 CAST 2 STN 39 CAST 2 STN 41 CAST 2 STN 43 CAST 2 STN 45 CAST 2 STN 47 CAST 2 STN 49 CAST 2
CTD has been converted to exchange using the new code and put online. The appropriate amount of files were not produced. The following CTD files were not converted because sumfile contains no navigational information for them i06s0096.3.wct i06s0096.wct i06s0097.2.wct i06s0097.wct i06s0098.2.wct i06s0098.wct i06s0099.wct
As per Don-Ha Min's e-mail I have corrected two errors in the I06S sumfile. station 23 cast 3 BE the latitude minutes were changed from 59 to 57 station 23 cast 3 BO, the max pressure was changed from 295 4 to 295.4 the edited sumfile is online and a copy of the old sumfile has been placed in the original directory. all references to this file have been updated.
I have encountered an error while loading the s04hy.txt for our CFC DQE work for s04_I06. It turns out that the position of 'QUALT1' on header is aligned at the end of the flag columns instead of beginning of flag columns ... The sample and bottle numbers are still entirely -9, so I can't compare with the revised CFC data set I got from the CFC PI. Tom Haine (now at Johns Hopkins) is the CFC PI for this cruise, and he has recently sent out the revised CFC data to the British data center. He says the center will forward the merged hydrographic data file to WHPO soon. Have you heard anything from BODC? I noticed another particular thing in the sea file of I06S as follows: i06shy.txt Sta.30 Cast 1 Btl.12 (1500m): ctd pressure, temperature and salinity reported as -9 yet with no flags
I just noticed some glitches in sum file of I06S cruise. Sta.23 Cast 3 ROS (1st row) lat: 57 39.89 S instead of 59 39.89 S ? Sta.23 Cast 3 ROS (2nd row) Max.Press: 295.4 instead of 295 4
replaced pdf and txt documents with newer versions. old files were replaced and moved to original. new files were put online.
added figs, linked tables and figs, data processing notes
The cast numbers in the .sum files in the stations listed above agree with the cast numbers in the .ctd files. Therefore I will change the .hyd file.
Hi Jim, Sure, I would be glad to look over the Indian Ocean data for you. Sarilee has started plotting up I01 for me to start on. - Arnold
I've reformatted the I06S CTD data files CIVA2_0491.csv through CIVA2_9991.csv I06S EXPOCODE 35MF103_1 CTD Stations 49-96 plus 998 & 999. 1. Changed comma separated value files received from Steve Diggs November 15, 2000, to WOCE format CTD files. CIVA2_0491.csv to i06sb0049.wct CIVA2_0501.csv to i06sb0050.wct etc. etc. CIVA2_0951.csv to i06sb0095.wct CIVA2_0961.csv to i06sb0096.wct CIVA2_9981.csv to i06sb0998.wct CIVA2_9991.csv to i06sb0999.wct 2. Plotted all files and ran wctcvt. No apparent errors. 3. Sarilee Anderson has already reformatted Stations 1 - 48. The two sets of reformatted CTD files should be put in to on zipped file for posting to the web. Dave Muus, November 21, 2000
The data file I just submitted, "I6S.C14" is NOT my data. I sent on request from Piers. I recieved the original file from V. Leboucher. This data is public and has been published: Leboucher, et al., 1999, Radiocarbon, 41(1), 51-73. In the original file, the casts were identified by a letter code. I replaced the letters with numbers corresponding to the hyd file at WHPO and then merged. The replacement scheme was: "S"=3 "I"=2 "P"=1 There was one id error in the original file which I fixed prior to merging. The errors are as reported with the original data. I carried out QC and assigned all flag values. The directory this information has been stored in is: 20000825.072602_KEY_I6S The format type is: ASCII The data type is: Other Type of Data Here is the information regarding the 'OTHER' format: French data submitted on request of P. Chapman, see e-mail The Bottle File has the following parameters: STNNBR, CASTNO, BTLNBR, DELC14, C14ERR, C14FLAG KEY, BOB would like the data PUBLIC. And would like the following done to the data: merge, on-line Any additional notes are: File "I6S.C14"
The quality of the Ba data from most WOCE legs in the Indian Ocean turned out to be quite poor; far worse than attainable analytical precision (+/-20% as opposed to 2%). We recorded many vials which came back with loose caps and evaporation associated with that seems to be the primary problem. The only hope I have of producing a decent data set is to run both Ba and a conservative element simultaneously and then relating that to the original salinity of the sample. We will be taking delivery on a high resolution ICPMS here at OSU sometime this winter which would make the project analytically feasible and economical. I do not presently have the funds in hand to do this and so have archived the samples for the time being. I don't think the WHPO would derive any benefit from the present data set. KKF
Needs new figs/txt needs reformatting
The I6 (HELLIUM) data are from the 1996 cruise (CIVA-2 cruise). The CIVA-1 helium samples were bad due to sampling problems (the clamps on the copper tubes were not properly closed and most samples suffered partial reequilibration with the atmosphere...).
i06s.note 19981223WHPOSIODM i06ssu.txt - MAX PRESS given in tenths of decibars (f6.1) instead of i5. Consequently header adjusted to put extra space between WIRE OUT and MAX PRESS. MAX PRESS values unchanged. EXPOCODES not yet changed.
We have found a mistake in the table of bottles data of CIVA 1 cruise (I6) occupied in 1993: the station 25 has to be replaced by the data attached (under excel format). We are working on CIVA 2 data 1996) and when it will be ready I will sent them to you.
I have put the reformatted CTD files for I06S in the anonymous ftp area on whpo in INCOMING. I compared all the files, but there were only 14 that were different from the originals I did in Sept. I only put those 14 stations there. There is also an i06s.notes file. CTD stations 6, 10, 13.3, 14.2, 18, 21, 32, 40, 45, 47, 47.3, 48, 49, and 52 were truncated in transfer in the original files. They are now complete and have been reformatted.
I received the I06S (1996 version) which is complete from Alain Poisson today on CDROM. This CDROM also contains all of the CTD data for I06-1993, so we can get Sailee/Dave Muus to correct the truncated stations from the aborted I06S effort.
Completed reformatting the ctd files. Only the headers needed information to make them complete. Added NO. RECORDS= value, and changed the station and cast numbers. The originator had all casts set to 1 and the station numbers (as pointed out by Lynne) were numbers like 11, 21, 33 where the first number is the station number and the second is the cast number, ie 33 is station 3, cast 3, etc. In most cases the originator reported more than one cast. There is not a standard in the files naming convention for this. I named the files i06sxxxx.wct for the deepest cast - usually cast 1. The other files were named i06sxxxx.x.wct, xxxx being the station number and the .x being the cast number.
in view of the age of the data you are mentionning, I consider that they should be made available in the largest possible form, provided their origin is described in the data files, CD Roms or plots, and to the largest possible population of scientists, provided it is asked to them they refer to the initial origin of the data when they use them. -- Sincerely yours, JF Minster
Station 25 on I06S has columns out of order (temperature and salinity switched etc etc). Can you please regrid all properties for I06S, leaving out station 25? It's too much trouble for me to correct the data set right now. Steve and Jerry - PLEASE keep this email in your comments for I06S which would be forwarded to a DQE or given to Dave Muus or Sarilee to fix before the data set is sent to a DQE. The data set should definitely be fixed before it is released to anyone else. The problem is in station 25 cast 1, where the columns are in a different order from all other casts on the section.
The .sum file now conforms with our new format EXCEPT for the max press. The original file had the maximum pressure to tenths (xxxx.x). I left it that way.
only have 22 of 58 stas
Files i06_sum.txt and i06_hyd.txt were reformatted to conform with what is, at this time, the WHP formats. This consisted mostly of adding spaces and shifting data. The following are other discrepancies that were found. Some that were obvious were "corrected" others were left as is for someone else to determine what should be done.--Sarilee Anderson, 3 Feb. 1998 i06_sum.txt: --record 136 longitude input as 29 60.0 - changed to 30 00.0 --record 420 max. pressure input as 288?2 - changed to 288.2 --records 516, 517, and 518 all had the date as 31393 - changed to 031393 i06_hyd.txt: --SAMPNO - these are strange numbers 10, 20 30,40,1750,2000, as if they were desired depths (pressure) for sample. Doesn't cause a problem, just strange. There are even some that have F-20 as a sample no, these are usually the deepest sample(s). --Station 12, cast 1 and cast 4 - these casts do not have CTDPRS, CTDTMP, CTDSAL, CTDOXY, THETA, SILCAT, NITRAT or PHSPHT. But they do have SALNY, OXYGEN, CFC-11, CFC-12, and TCARBN. WOCECVT will not convert them because there are no pressures (depths) --Station 25, records 720 to 731, sample 325 bottle 12 to sample 1600 bottle 1. data screwed up. THETA, SALNY, OXYGEN, and SILCAT columns do not have the correct values. QUALT1 flags not much help in determining what the problem might be. Values aren't even close to what they should be. Some values might be in the wrong columns, but that does not account for everything. --Station 28, record 811 (last record in file) is incomplete. The .hyd file stops at sta. 28, but the .sum file indicates there should be 52 stations. In the following stations the cast number in the .sum file does not agree with the cast number in the .hyd file. Station #s cast #s in .sum cast #s in .hyd 2 1 and 3 1 and 2 3 1 and 3 1 and 2 7 1 and 3 1 and 2 9 1 and 3 1 and 2 11 1 and 3 1 and 2 15 1 and 3 1 and 2 17 1 and 3 1 and 2 19 1 and 3 1 and 2 21 1 and 3 1 and 2 23 1 and 3 1 and 2 25 1 and 3 1 and 2 27 1 and 3 1 and 2 I'm guessing the .hyd is correct and the .sum is incorrect. But I did not change either of them.
